LPS-RK-350SP - 350Amp Fuse

LPS-RK-350SP - 350Amp Fuse

When you're replacing or specifying a 350A fuse, amperage alone doesn't tell the whole story. The fuse class, AC and DC voltage ratings, interrupting capacity, operating characteristics, connection style, and physical size must match the equipment. The Eaton Bussmann series LPS-RK-350SP is a 350A Class RK1 time-delay, current-limiting fuse rated for 600VAC and 300VDC. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPS-RK-350SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 350A Class RK1 configuration: Combines a 350-amp rating with the manufacturer's specified Class RK1 construction, providing important identification points when matching an existing fuse.
• Time-delay operation: Eaton identifies the LPS-RK-350SP as a time-delay fuse. Match this characteristic to the circuit and equipment requirements rather than selecting by amperage alone.
• Current-limiting fuse: Current-limiting operation is specified by Eaton for this catalog number.
• Dual-element construction: Uses the manufacturer's specified dual-element configuration.
• 600VAC / 300VDC voltage ratings: Suitable for compatible equipment requiring the corresponding AC or DC voltage rating.
• Blade end × blade end connection: An important physical characteristic to verify when confirming form and fit.
• Non-indicating configuration: Eaton identifies this fuse as non-indicating.

Where It Works Best

The Eaton Bussmann LPS-RK-350SP 350A Class RK1 fuse is intended for compatible electrical equipment requiring its specific combination of a 350A rating, 600VAC / 300VDC voltage ratings, Class RK1 configuration, time-delay operation, current-limiting characteristics, dual-element construction, and blade-end × blade-end connection. The electrically isolated end cap is another manufacturer-specified feature to include in the compatibility check.
